The Linux console only allows one current tty. When you switch
away from the X server, it relinquishes the display and restores
text mode, it no longer has access to the display until you
switch back. When you switch to the other server, it has
control.
It doesn't matter if these are 2 individual video cards or not,
as there can only be one current tty.
The 2.6.x kernel has features to get past this limitation,
however I don't believe the marriage of the kernel and X server
is quite ready yet for this to actually work. Someone else can
comment on that or not.
There is an ugly hack somewhere on the net which IIRC hacks both
the kernel and X server to allow a kludged solution to do this,
but it is just that, a "works for the guy who hacked it together"
kludge until something more proper is ready for regular usage.
I don't remember what it is called, but either someone else
reading this will know what I'm talking about and post a URL, or
you can probably find it without much effort on google.
Hope this helps.
